EQUALIZING-TEUCK FOR CRANE-TROLLEYS.

LGSQAQQ.

To all whom it may concern:

Be it known that 1, CHARLES H. TUCKER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Equalizing-Truck for Crane- Trolleys; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates particularly to crane trolleys of the underslung or suspended frame type, but is not restricted to such use, as it may be used for any purpose for which it may be adapted or appropriate.

The object of my invention is the provision, in a trolley of this character, of an equalizing truck which is simple and inexpensive of manufacture, strong and durable in its construction, and has the trolley frame suspended therefrom in such manner as to permit a free limited rocking of the trucks relative thereto, and which also obviates the use of the shock-absorbing springs customarily employed in connection with the trucks of trolleys of this class, thus enhancing the practicability and commercial value thereof.

The invention is fully described in the following specification and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a trolley embodying my invention, with the near truck wheels removed. Fig. 2 is a top plan thereof with portions broken away. Figs. 3 and 4 are different enlarged elevations of portions of a truck and the suspended trolley frame with parts broken away and in section, and Fig. 5 is a reduced top plan view of the end member of a truck with the truck axles and wheels attached thereto.

Referring to the drawings, 1, 1 designate the side beams, and 2 the crossgirts of a trolley frame of any suitable form and construction, which is provided, in the present instance, at the ends of the beams 1 with upstanding hanger-plates 3, which are piv- Specification of Letters Patent.

otally suspended from the end beams or members of the trolley trucks, as shown.

Each of the end beams of the trucks comprises a pair of plates or members 4 and 5 of preferably substantially duplicate form, which are rigidly secured together at their end portions in laterally abutting relation by bolts 6, or in any other suitable manner. The inner sides of these plates are recessed in registering relation to form a centrallydisposed vertical socket 7 therebetween into which the upper end of an associated hanger-plate 3 is intended to fit. The hanger-plates 3 are pivotally hung from within the sockets 7 of the truck ends by short shafts 8, which extend across the central portions of such sockets through regis tering openings in the hanger-plates 3 and plates 4 and of the truck ends. The sockets 7 of the truck ends are of greater breadth than the hanger-plates 3 to permit the truck ends to have equalizing rocking action relative thereto, with the shafts 8 as their rocking axes. The plates 4 and 5 of the truckends, in addition to being secured together by the bolts 6, are also preferably connected by bolts 9,'which project through openings 10 in the plates 8, which openings are of greater diameter than the bolt shanks to enable the plates to rock relative thereto. The truck end plates 1 and 5 are preferably provided on their outer sides with strengthening webs or flanges 11, as shown.

The truck axles 12, which are two in number for each truck and carry the wheels 13 at their outer ends without the truck end members 4-5, are journaled adfacent to their ends in the opposite end portions of such members. In the present instance the ends of the members 4l5 are recessed at their lower portions to provide the over hanging shoulders 14 against which the bearing-blocks 15, which rest upon the axles, have their upward thrusts, as is apparent. The axles 12 are held to the blocks 15-by the t-shaped retaining boxes 16, which bolt at top and bottom to the respective portions of the ends of the members 45, as shown, and also form boxes for holding oiled waste or other lubricant.

It will be noted that the mounting of the truck ends t-5 for pivotal equalizing movements relative to the hanger plates 3 of the trolley frame enables a motor 17 which is mounted on the cross-girts 2 of the (:(zuzhiiiulioin 4': Much njovulecl i In cou'ihuiuiion. :1 l' c ineinhers nojeclinfg upwardly (herei we 'l'llUUliS he 'ingg vertically socketecl a P5 into which respective ones of l each truck, to have C single 'li mesh with o vposing gears 19, 12 12 of the ussocin ecl of? course the Lexie of i ineinent with the uxlee to be driven gear.
